Hello, I've been running a iptables + NAT firewall for some time now, suddenly, some of my most common e-mail destinations are not working, I go and check on another host I have directly on the internet and I can connect with no trouble at all to those sites, if I check on my netstat -at (on the firewall) the connections stay at SYN State all the time.
Anybody experienced anything like this before? Thanks in advance for any help or suggestions. Regards, Omar
